[SOLVED] 8700k's lower cpu usage than 9700k

[alohamasto]

so this video https://www.youtube.com/watch?v=rvDU7xGHpNo&t= shows that the 8700k uses significant less resources than the 9700k in almost every game . so that means that the 8700k has less chances of reaching 100% resulting in stuttering and fps drops when streaming/recording while gaming ?

12 threads vs 8, so it is going to be able to handle more multitasking.

Kind of the way I have always perceived it. There are going to be some games where multi-threading is useful.

I didn't watch the whole video. Do we know the status of the spectre/meltdown patches on both of these chips? This just could be the difference between branch prediction being on on the older processor and off on the newer one.

Reviews of the 9700k have it typically fairly evenly matched with the 8700k in highly threaded workloads. Which makes sense given that from what I've heard hyperthreading adds maybe 30-40% performance absolute best case scenario, whereas the 9700k has 33% more cores.

If you want to stream, I wouldn't use either CPU.
